The device is qualified to meet the JEDEC standard for
Pb-Free assembly. The temperatures and time
intervals listed are based on the Pb-Free small body
requirements. The VS-720 device is hermetically
sealed so an aqueous wash is not an issue.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and
IR reflow simulation. The VS-720 family is capable of meeting the following qualification tests:
Environmental Compliance

Handling Precautions
Although ESD protection circuitry has been designed into the VS-720 proper precautions should be taken when
handling and mounting. VI employs a human body model (HBM) and a Man Man method (MM) for ESD
susceptibility testing and design protection evaluation.
